jfinal版本4.9.08，activiti7.1

1、在创建好的jfinalmaven版本下，pom.xml添加：

 <dependency>

            <groupId>org.activiti</groupId>

            <artifactId>activiti-engine</artifactId>

            <version>7.1.0.M6</version>

        </dependency>

        <dependency>

            <groupId>org.activiti</groupId>

            <artifactId>activiti-bpmn-model</artifactId>

            <version>7.1.0.M6</version>

        </dependency>

        <dependency>

            <groupId>org.activiti</groupId>

            <artifactId>activiti-bpmn-converter</artifactId>

            <version>7.1.0.M6</version>

        </dependency>

        <dependency>

            <groupId>org.activiti</groupId>

            <artifactId>activiti-json-converter</artifactId>

            <version>7.1.0.M6</version>

        </dependency>

        <dependency>

            <groupId>org.activiti</groupId>

            <artifactId>activiti-bpmn-layout</artifactId>

            <version>7.1.0.M6</version>

        </dependency>

2、创建插件类ActivitiPlugins

import org.activiti.engine.ProcessEngine;

import org.activiti.engine.ProcessEngineConfiguration;

import org.activiti.engine.ProcessEngines;

import com.jfinal.plugin.IPlugin;

import com.jfinal.plugin.activerecord.IDataSourceProvider;

public class ActivitiPlugins implements IPlugin {

@Override

public boolean start() {

if (isStarted) {

return true;

}

processEngineConfiguration = ProcessEngineConfiguration

.createStandaloneProcessEngineConfiguration()

.setDatabaseType("mysql")

.setDataSource(this.dataSourceProvider.getDataSource())

.setTransactionsExternallyManaged(true) // 使用托管事务工厂

.setDatabaseSchemaUpdate(

ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);// 数据库中没有表则创建表

// .buildProcessEngine();//开启流程引擎

// processEngine.getRepositoryService();

// configuration

System.out.println("流程引擎111:" + buildProcessEngine());

// System.out.println("流程部署服务："+processEngine.getRepositoryService());

isStarted = true;

// ProcessEngines.init();//开启流程引擎

System.out.println("启动流程引擎.......");

return isStarted;

}

@Override

public boolean stop() {

ProcessEngines.destroy();// 关闭流程引擎

isStarted = false;

return true;

}

// 开启流程服务引擎

public static ProcessEngine buildProcessEngine() {

if (processEngine == null)

if (processEngineConfiguration != null) {

processEngine = processEngineConfiguration.buildProcessEngine();

}

return processEngine;

}

private static ProcessEngine processEngine = null;

private static ProcessEngineConfiguration processEngineConfiguration = null;

// 基本属性 url、user、password

private IDataSourceProvider dataSourceProvider = null;

private boolean isStarted = false;

public ActivitiPlugins(IDataSourceProvider dataSourceProvider) {

this.dataSourceProvider = dataSourceProvider;

}

// get/set方法

public IDataSourceProvider getDataSourceProvider() {

return dataSourceProvider;

}

public void setDataSourceProvider(IDataSourceProvider dataSourceProvider) {

this.dataSourceProvider = dataSourceProvider;

}

}

3、在启动类中，configPlugin(Plugins me)方法注册ActivitiPlugins插件

//activiti 插件配置

DruidPlugin druidPlugin2 = new DruidPlugin(p.get("jdbcUrl2"), p.get("user"), p.get("password").trim());

me.add(druidPlugin2);

ActivitiPlugins activitiPlugins = new ActivitiPlugins(druidPlugin2);

me.add(activitiPlugins);

4、自己创建对应数据库，并且在jfinal配置文件修改对应数据库连接信息，以下是我自己配置：

jfinal启动类默认配置：我的配置文件是config.txt，在src/main/resources下面

static void loadConfig() {

if (p == null) {

p = PropKit.useFirstFound("demo-config-pro.txt", "config.txt");

}

}

config.txt：

# config

jdbcUrl = jdbc:mysql://localhost/数据库名?characterEncoding=utf8&useSSL=false&serverTimezone=GMT

user = root

password =123456

jdbcUrl2 = jdbc:mysql://localhost/数据库名?characterEncoding=utf8&useSSL=false&serverTimezone=GMT

说明：jdbcUrl2是创建一个新的数据库，专门存放activiti自动生成的表，jdbcUrl是自己另外一个业务系统数据库，两者分开，方便查看调试。

5、最后运行启动类，可以发现对应数据库自动生成25张表，到此就可以快乐玩转activiti7
